Abstract (en)

[origin: WO2010104520A1] Broad band structures (10, 10', 10") for surface enhanced Raman spectroscopy are disclosed herein. Each embodiment of the structure (10, 10', 10") is made up of a metal layer, and a dielectric layer (16A, 16S, 16P) established on at least a portion of the metal layer. The dielectric layer (16A, 16S, 16P) has a controlled thickness that varies from at least one portion of the dielectric layer (16A, 16s, 16p) to at least another portion of the dielectric layer. Nanostructures are established on the dielectric layer (16A, 16S, 16P) at least at the portion and the other portion, the nanostructures thus being configured to exhibit variable plasmon resonances.
